Description

  The present invention relates to a drive device for an opening / closing body mounted on a vehicle.

  In a drive device for an opening / closing body for an automobile, such as a window regulator that raises / lowers a window glass or a door opening / closing device that opens / closes a sliding door, the wire is moved (pulled or loosened) by rotation of a winding drum around which the wire is wound. The structure that drives the opening / closing body (window glass or sliding door) is often used. A spiral groove around which the wire is wound is formed on the outer peripheral surface of the winding drum. The end of the cylindrical outer tube is connected to the drum housing that houses the take-up drum, and the wire extended from the spiral groove of the take-up drum passes through the passage in the drum housing to the insertion hole in the outer tube. It is inserted so that it can move forward and backward.

  In this type of driving device, when the winding drum rotates, the wire swings in the rotation axis direction of the winding drum according to the inclination of the spiral groove. At this time, if the deflection amount (deflection angle) of the wire is large, the wire may interfere with the edge of the insertion hole at the end surface portion of the outer tube, and the wire may be damaged by repeated driving. As a countermeasure against this, a bush member that can insert the end of the outer tube is provided as a member separate from the drum housing, and a steady hole that gradually increases the inner diameter with increasing distance from the end of the outer tube is provided in the bush member. A structure is known in which the outer tube is formed and connected to the drum housing via a bush member (Patent Document 1). When the winding drum rotates, the deflection angle of the wire is limited by the inner surface of the steady hole, so that the wire can be protected.

A pulley bracket 30 is fixed near one end of the guide rail 11 in the longitudinal direction, and a guide pulley 17 is rotatably supported on the pulley bracket 30 via a pulley support shaft 19. The wire 15 extends from the slider base 14 along the guide rail 11 toward one end of the guide rail 11, and is supported by a wire guide groove formed on the outer peripheral surface of the guide pulley 17. The guide pulley 17 rotates about the pulley support shaft 19 as the wire 15 advances and retracts. A wire guide member 18 is provided near the other end of the guide rail 11 in the longitudinal direction, and the wire 16 extends from the slider base 14 along the guide rail 11 toward the other end of the guide rail 11 and the wire guide member 18. You will be guided to 18. The wire guide member 18 is fixed to the guide rail 11, and the wire 16 is supported along the wire guide groove formed in the wire guide member 18 so as to be able to move forward and backward.

  The wires 15 and 16 output from the guide pulley 17 and the wire guide member 18 are inserted into the tubular outer tubes 21 and 22, and are wound on the winding drum 23 provided in the drum housing 20 to which the outer tubes 21 and 22 are connected. It is wound. As shown in FIGS. 7 and 8, the winding drum 23 has a cylindrical shape, and a shaft fitting hole 24 penetrating in the axial direction is formed in the central portion thereof. Serrated serrations are formed on the inner surface of the shaft fitting hole 24. A spiral groove 25 around which the wires 15 and 16 are wound is formed on the outer peripheral surface of the winding drum 23. The spiral groove 25 changes its position in the axial direction of the winding drum 23 while turning along the outer peripheral surface of the winding drum 23. The formation range H of the spiral groove 25 in the axial direction of the winding drum 23 is shown in FIG.

  A motor unit (driving member) 26 (FIGS. 1 to 3) is attached to the drum housing 20. The motor unit 26 includes a motor 27, a gear box 28 having a reduction gear train that transmits the rotation of the output shaft of the motor 27 while decelerating the rotation, and a rotation driving force of the motor 27 via the reduction gear train of the gear box 28. A fitting shaft (not shown) for transmitting is transmitted. The motor unit 26 has a cover portion 29 that covers an opening portion of the drum housing 20 described later, and the fitting shaft projects from the cover portion 29 and fits into the shaft fitting hole 24 of the winding drum 23. The fitting shaft is formed with serrations that fit into the serrations of the shaft fitting hole 24. When the motor 27 is driven in this fitted state, the winding drum 23 rotates together with the fitting shaft.

  One end of the outer tube 21 is connected to the pulley bracket 30 and the other end is connected to the drum housing 20, so that the wire 15 can be moved back and forth within the outer tube 21 whose both ends are defined. One end of the outer tube 22 is connected to the wire guide member 18 and the other end is connected to the drum housing 20, so that the wire 16 can be moved back and forth within the outer tube 22 having both end positions defined. Insertion holes 50 (FIG. 9) are formed in the outer tubes 21 and 22 so as to penetrate in the longitudinal direction, and the wires 15 and 16 are inserted into the insertion holes 50. An end of the outer tube 21 on the side connected to the pulley bracket 30 is a rail side end 21a, and an end on the side of the outer tube 22 connected to the wire guide member 18 is a rail side end 22a. Further, the ends of the outer tubes 21 and 22 that are connected to the drum housing 20 side are referred to as drum-side ends 21b and 22b.

  The drum housing 20 is fixed to a door panel (inner panel). When the winding drum 23 is rotated in the forward and reverse directions by the driving force of the motor 27, one of the wires 15 and 16 increases the winding amount of the winding drum 23 around the spiral groove 25, and the other of the wires 15 and 16 increases the spiral groove of the winding drum 23. 25, and the slider base 14 moves along the guide rail 11 due to the relationship of pulling and loosening of the pair of wires 15 and 16. The window glass moves up and down according to the movement of the slider base 14.

  Hereinafter, the drum housing 20 to which the outer tubes 21 and 22 are connected will be described. As shown in FIGS. 4 to 6, the drum housing 20 has a drum housing portion (housing portion) 31 and a pair of outer tube insertion portions 32 and 33. The drum accommodating portion 31 forms a space surrounded by a bottom portion 34 and a cylindrical standing wall 35 formed around the bottom portion 34, and an opposite side of the bottom portion 34 is opened as an accommodating portion opening 36. A drum support seat 37 (FIG. 5) is provided on the bottom portion 34. The winding drum 23 has one end placed on the drum support seat 37 and is inserted into the drum accommodating portion 61. The drum support seat 37 is provided with a cylindrical shaft projection 37a (FIG. 5), and the winding drum 23 is formed with a smooth cylindrical surface 24a (FIG. 7) in a part of the shaft fitting hole 24. The shaft protrusion 37a is inserted into the cylindrical surface 24a, and the cylindrical surface 24a is brought into sliding contact with the shaft protrusion 37a, so that the winding drum 23 is rotatably supported. The rotation shaft 23x, which is the rotation center of the winding drum 23 in the state of being housed in the drum housing portion 61, is shown by a chain line in FIGS. When the driving force of the motor 27 is transmitted, the winding drum 23 rotates about the rotation shaft 23x.

  In the drum housing 20, a wire passage groove (wire passage portion) 40 and a wire passage groove (wire passage portion) 41 communicating with the drum housing portion 31 are in different directions (a pulley bracket 30 and a wire guide in a completed state of the window regulator 10). The outer tube insertion portion 32 is provided at the tip of the wire passage groove 40, and the outer tube insertion portion 33 is provided at the tip of the wire passage groove 41.

  The wire passage groove 40 and the wire passage groove 41 have substantially the same configuration, and elements common to the wire passage groove 40 and the wire passage groove 41 are indicated by the same reference numerals in the drawings. The wire passage grooves 40, 41 are groove-shaped portions that project from the drum housing portion 31 in a direction intersecting (substantially orthogonal to) the rotary shaft 23x, and are connected to a bottom portion 42 continuous with the bottom portion 34 of the drum housing portion 31, respectively. It has a pair of side walls 43 and 44 which are erected from the bottom portion 42 in the direction along the rotation axis 23x (the protruding direction of the standing wall 35). A passage groove opening 45 is formed in a top surface portion facing the bottom portion 42. The passage groove opening 45 is an opening that is continuous with the housing opening 36 of the drum housing 31.

  The drum side end 21b of the outer tube 21 can be inserted into the outer tube insertion portion 32, and the drum side end 22b of the outer tube 22 can be inserted into the outer tube insertion portion 33. FIG. 6 shows an insertion shaft 32x that is the insertion direction of the drum side end portion 21b with respect to the outer tube insertion portion 32 and an insertion shaft 33x that is the insertion direction of the drum side end portion 22b with respect to the outer tube insertion portion 33.

  The outer tube insertion portion 32 and the outer tube insertion portion 33 have substantially the same configuration, and elements common to the outer tube insertion portion 32 and the outer tube insertion portion 33 are indicated by the same reference numerals in the drawings. Insertion grooves 46 are formed inside the outer tube insertion portions 32 and 33 so as to penetrate in the directions of the insertion shafts 32x and 33x. The insertion groove 46 communicates with the wire passage grooves 40 and 41, and a stepped insertion restriction surface 47 is formed near the boundary between the wire passage grooves 40 and 41 and the insertion groove 46. The end surfaces of the drum side end portions 21b and 22b of the outer tubes 21 and 22 inserted into the outer tube insertion portions 32 and 33 come into contact with the insertion regulation surfaces 47, respectively, and the outer tubes 21 to the outer tube insertion portions 32 and 33, The insertion position of 22 is determined (see FIG. 9). The passage groove openings 45 of the wire passage grooves 40, 41 are formed continuously up to the outer tube insertion portions 32, 33. The width of the passage groove opening 45 in the outer tube insertion portions 32, 33 is smaller than the diameter of the outer tubes 21, 22, and the drum-side end portions 21b, 22b of the outer tubes 21, 22 inserted in the outer tube insertion portions 32, 33. Are designed not to fall off through the passage groove openings 45.

  At the time of assembling the window regulator 10, the wires 15 and 16 protruding from the end faces of the drum side end portions 21b and 22b of the outer tubes 21 and 22 are passed through the passage groove openings 45 and the insertion grooves 46 of the outer tube insertion portions 32 and 33 and the wire passages. The drum-side end portions 21b and 22b are inserted into the grooves 40 and 41, and are inserted into the insertion grooves 46 of the outer tube insertion portions 32 and 33 along the insertion shafts 32x and 33x. The end surfaces of the drum side end portions 21b and 22b come into contact with the insertion restriction surface 47, and the positions of the outer tubes 21 and 22 in the insertion axis 32x and 33x directions are determined. The wires 15 and 16 are guided into the drum housing portion 31 through the wire passage grooves 40 and 41, and are wound around the spiral groove 25 on the outer peripheral surface of the winding drum 23. In the assembled state (FIGS. 1 to 3 and 9), the wires 15 and 16 can move forward and backward with respect to the outer tubes 21 and 22 in the insertion hole 50 (FIG. 9), and The winding amount of the wires 15 and 16 around the spiral groove 25 changes according to the rotation.

  Further, the motor unit 26 is attached to the top surface side of the drum housing 20. The cover portion 29 of the motor unit 26 closes the housing portion opening 36 and the passage groove opening 45 of the drum housing 20 to prevent the take-up drum 23 from falling out of the drum housing portion 31. By mounting the motor unit 26, the fitting shaft (not shown) on the motor unit 26 side fits into the shaft fitting hole 24 as described above, and the driving force of the motor 27 can be transmitted to the winding drum 23. .

  In the window regulator 10 in which the wires 15 and 16 are arranged as described above, when the winding drum 23 rotates, the feeding position of each wire 15 and 16 from the spiral groove 25 changes in the direction along the rotation axis 23x. The drum housing 20 has a first steady-state portion (a steady-state portion, a first steady-state portion, a first steady-state portion) in each of the wire passage groove 40 and the wire passage groove 41, as a shake prevention means for restricting the shake of the wires 15 and 16 in the direction along the rotation axis 23x. And a second steady portion (second steady portion, second steady portion) 52.

  In FIG. 9, one end D1 and the other end D2 of the forming range H (FIG. 8) of the spiral groove 25 of the winding drum 23 and the forming range of the insertion hole 50 of the drum side end 22b of the outer tube 22 are shown in FIG. One end E1 and the other end E2 are shown. An imaginary line connecting one end D1 on the spiral groove 25 side and one end E1 on the insertion hole 50 side is F1, and an imaginary line connecting the other end D2 on the spiral groove 25 side and the other end E2 on the insertion hole 50 side is F2. As shown in FIG. 9, the wire 16 is supported in the drum housing 20 by the winding drum 23 (spiral groove 25) and the drum-side end portion 22b (insertion hole 50) of the outer tube 22, and the wire passage groove 41 therebetween. Does not receive the support of the winding drum 23 or the outer tube 22. Therefore, when the steadying means is not provided, the wire 16 may shake in a range surrounded by the virtual line F1 and the virtual line F2 (referred to as a shakeable range M). 9 shows the relationship between the wire 16 and the wire passage groove 41, the wire 15 and the wire passage groove 40 have the same relationship.

  The first steady rest 51 is a protrusion provided on the side wall 43, and is provided at a position inside the shakeable range M with respect to the virtual line F1 in the direction along the rotation axis 23x (see FIG. 9). . Further, when viewed along the rotation axis 23x as shown in FIG. 6, the first steadying portion 51 of the wire passing groove 40 is at a position overlapping the insertion shaft 32x, and the first steadying portion 51 of the wire passing groove 41 is located. Is at a position overlapping the insertion axis 32x. Therefore, the wire 15 routed along the insertion axis 32x in the wire passage groove 40 and the wire 16 routed along the insertion axis 33x in the wire passage groove 41 are both in the first steady rest portion 51. Thus, the one shake amount along the rotation axis 23x is limited. Specifically, the shake amount is limited to a range (position near the virtual line F2) narrower than the virtual line F1 of the shakeable range M.

  The second steady rest 52 is a protrusion provided on the bottom 42, and is provided at a position inside the shakeable range M with respect to the virtual line F2 in the direction along the rotation axis 23x (see FIG. 9). . Therefore, both the wire 15 routed in the wire passing groove 40 and the wire 16 routed in the wire passing groove 41 limit the other runout amount along the rotary shaft 23x by the second steady rest 52. To be done. Specifically, the shake amount is limited to a range (position near the virtual line F1) narrower than the virtual line F2 of the shakeable range M.

  In this way, by limiting the deflection amount (deflection angle) of the wires 15, 16 in the direction along the rotation axis 23x by the first steady portion 51 and the second steady portion 52, the durability of the wires 15, 16 is improved. Can be made. In particular, in the insertion portion of the outer tubes 21, 22 (drum side end portions 21b, 22b) where the swingable range M is the narrowest into the insertion hole 50, rubbing of the wires 15, 16 against the edge portion of the insertion hole 50 is prevented. It can be effectively prevented. Since the deflection of the wires 15 and 16 is limited by the first steady portion 51 and the second steady portion 52 formed in the drum housing 20, it is not necessary to separately provide a steady member or mechanism, and the structure Is simple and can be obtained at low cost.

  The first steadying portion 51 and the second steadying portion 52 are located closer to the outer tubes 21 and 22 than the winding drum 23 in the longitudinal direction of the wire passage grooves 40 and 41 (the extending direction of the wires 15 and 16). It is arranged at a position close to the ends 21b and 22b. This arrangement is advantageous in that the runout width of the wires 15 and 16 can be controlled at a position close to the edge of the insertion hole 50 of the outer tubes 21 and 22 where the wires 15 and 16 tend to rub.

  The drum housing 20 having the housing opening 36 and the passage groove opening 45 opened in the direction along the rotary shaft 23x is preferably manufactured by two molds that relatively move in the direction along the rotary shaft 23x. Here, the first steady rest 51 and the second steady rest 52 are located at different positions in the longitudinal direction of the wire passage grooves 40, 41. Further, through holes 53 are formed in the bottom portions 42 of the wire passage grooves 40, 41 at positions facing the first steady rest portion 51 in the direction along the rotary shaft 23x. With this configuration, the first steady rest 51 and the second steady rest 52 can be formed together by the two molds that relatively move in the direction along the rotary shaft 23x, and thus the drum housing. 20 productivity is improved.

  As shown in FIG. 6, the width of the passage groove openings 45 of the wire passage grooves 40 and 41 is widened in the portion where the first steady rest 51 is formed, and the width between the first steady rest 51 and the side wall 44 is increased. A gap 45a (FIG. 6) is formed in the gap. Therefore, the wires 15 and 16 can be inserted into the wire passage grooves 40 and 41 through the gap 45a without being obstructed by the first steady rest 51. As shown in FIGS. 4 and 5, the first steady rest 51 has a taper surface 51a in the inclination direction that facilitates guiding the wires 15 and 16 to the gap 45a side.

  The present invention has been described above based on the illustrated embodiments, but the present invention is not limited to the illustrated embodiments, and improvements and modifications can be made without departing from the spirit of the invention. For example, in the illustrated embodiment, both the first steady portion 51 and the second steady portion 52 are provided in the drum housing 20, but at least one retainer is provided in the motor unit 26 assembled to the drum housing 20. You can also Specifically, since the cover portion 29 of the motor unit 26 has a shape that closes the passage groove opening 45 (constituting a part of the wire passage grooves 40 and 41), it corresponds to the first steady rest portion 51. The steady rest may be provided on the cover 29 instead of the drum housing 20.

  In the illustrated embodiment, the first steady rest 51 is provided on the side wall 43 of the wire passing grooves 40, 41, but the first steady rest 51 can be provided on the opposite side wall 44.

  In the drum housing 20 of the illustrated embodiment, the housing opening 36 of the drum housing 31 and the passage groove openings 45 of the wire passage grooves 40 and 41 open in the same direction, but the housing opening 36 and the passage groove opening 45 are The present invention can also be applied to a drum housing of a type that opens in opposite directions in the direction along the rotary shaft 23x.

  In the illustrated embodiment, a first steady portion 51 that limits the swing of the wires 15 and 16 in the first direction (the opening direction of the passage groove opening 45) in the direction along the rotation axis 23x of the winding drum 23, The second steady portion 52 is provided to limit the swing of the wires 15 and 16 in the second direction opposite to this (the direction of the bottom portion 42 of the wire passage grooves 40 and 41). This structure is excellent in that it can protect the wires 15 and 16 swaying in any direction due to the rotation of the winding drum 23, but the present invention is excellent only in one of the directions along the rotation axis 23x. This is true even if the configuration limits the shake.

  Further, in the illustrated embodiment, the wire passage groove 40 and the wire passage groove 41 in the drum housing 20 have a substantially common structure, which is a condition in which the wires 15 and 16 can be shaken in the same size. Although the first steady rest portion 51 and the second steady rest portion 52 having a common structure are provided in both the wire 40 and the wire passage groove 41, the condition of the shake amount of the wire 15 and the wire 16 (the shakeable range M in FIG. 9). When the width and the like are different, the specs (shape and arrangement) of the steady portion provided in the wire passage groove 40 and the steady portion provided in the wire passage groove 41 may be different.
